Question
[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
|
The production of mature mRNA in eukaryotes involves
|
|
cutting introns out and spicing exons together
|
|
|
adding the 5’ cap
|
|
|
adding the 3’ poly A tail
|
|
|
all of these are correct
|
Explanation:
Detailed explanation-1: -Final answer: b. exons appear but introns do not appear in the mature RNA.
Detailed explanation-2: -In eukaryotes, transcription produces a pre-mRNA molecule that be processed into mature mRNA by the addition of a 5′ cap, a 3′ poly-A tail, and through RNA splicing. At the end of eukaryotic transcription, a pre-mRNA molecule is formed.
Detailed explanation-3: -Capping at the 5’ end. Addition of a poly(A) tail at the 3’ end. Splicing to remove introns. 04-Aug-2021
